ZvGAiN'A. 87 



antennae of the male are nearly twice as long as in Notata, and not placed so closely together ; 

 the antennae of the female are strongly serrated for their entire length. Expands i \ inches. It 

 is found in Andalusia in June and July. The variety Siibsolana (Staud.), from South-Eastern 

 Europe, is dark greenish-blue, with no traces of golden-yellow. (/. Biidensis, Speyer, from 

 Hungary, Sarepta, and Armenia, has very short antenna ; those of the male formed nearly as 

 in Cognata, and those of the female scarcely serrated at all.) 



B. The antenncB thickened hito a club at the extremity ; the pectinations on those of the male 

 become sho7'ter towards the club, and there cease. 



*/. /. Statices (Linn.), (Green Forester). — Fore-wings broad and triangular, rather thickly 

 scaled, and shining green ; hind-wings grey ; body shining green, and abdomen sometimes golden- 

 red ; antennae short, only extending as far as the middle of the costa of the fore-wings ; the 

 pectinations very oblique on the antennae of the male, and close together. The female is much 

 smaller than the male. The bluish variety Mannii (Led.) is found in South Europe, and the 

 var. Crassicornis (Staud.), with thicker body and much thicker antennae, is found in Greece. 

 Expands from i to ij inches. The commonest species of the genus, occurring in meadows and 

 flowery glades throughout Europe from June to August. It is local in Britain, but is found 

 in many localities in England and Ireland, and at Oban in Scotland. The larva is ashy-grey, 

 with a row of triangular black spots on the back and a reddish stripe on the sides, bordered above 

 with white. It feeds on sorrel, mining in both sides of the leaf when )'oung ; when nearly 

 full-grown, it may be found hidden under the leaves in May and June. The moth is figured 

 at PI. 21, Fig. 3. 



8. /. Heydenreichii (Led.). — Larger than Statices, the wings still more densely scaled ; the 

 fore -wings rather narrower, shining bluish-green ; the hind-wings blackish. Head and thorax 

 fine blue, abdomen dark green ; the antennae long, reaching as far as two-thirds of the length 

 of the costa. Expands about i^ inches. It inhabits South-Eastern Europe, and is perhaps 

 not sufficiently distinct from Statices. 



*9. /. Geryon (Hiibn.). — Very like Statices, but smaller (expands rather less than i inch), 

 and the two sexes are of equal size. The fore-wings are narrower and of more equal breadth, 

 and are thickly scaled. They are green, more or less golden, but never blue. The hind-wings 

 are blacker, being more opaque. The antennae are shorter and thicker. This species has been 

 overlooked, but appears to be widely distributed in Central and Western Europe in June and July. 

 It frequents the short grass of dry hill-sides and similar localities ; and the larva, which feeds on 

 Hclianthemtnn vulgare, is a miner when young. 



10. /. Chrysocephala (Nick.). — Also very like Statices, but the pectinations of the antennae 

 of the male are less oblique and are separated. Both sexes are of the size of Geryon. The 

 head is golden-red, and the fore-wings are very thinly scaled, and duller coloured than in the 

 allied species. This insect is found in the high Alps in July, and may be an Alpine variety of 

 either Statices or Geryon. 



GENUS III. — ZYG^NA (FABR.). 



Body and fore-wings blackish-blue or green, with bright red, white, or, more rarely, yellow 

 spots, arranged in pairs as follows : — Two spots at the base, the first (spot i) close to the costa, 

 and the second (spot 2) just below it ; one spot before the middle below the costa (spot 3) ; 

 one below and rather behind it, nearly in the middle of the wing, but nearer to the inner 

 margin (spot 4) ; one spot below the costa, placed at three-quarters of the length of the wing 

 upon the disco-cellular nervule (spot 5) ; and often another before the middle of the hind margin
